SPRING-WHEEL FOR HECTOR-CAB" A3331) OTIBZER VEHICLES.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed July 23, 1907. Serial No. 385,130.

T all whom it may concern:

Be it known that I, EMILIO RonniGUinz, a subject of the King of Spain, residing a Chiswick, London,England, have invented new and useful improvements in Spring- Whecls for Motor-Cars and other Vehicles,

' of which the lollowing is a specification.

This invention relates to spring wheels for use with motor cars and other vehicles.

The object of the present invention is to construct an elliciently resilientwheel adapt ed for employment i1 connection with hicles and consists of the features ol construction and combination and arrangcmei'it ot parts hereinafter described.

in order that the said invention may be clcariy understood and readily carried into ellect, I will proceed to describe the same with reference to the examples illustrated in the accompanying drawings, in which z- Figure 1 represents a view of a portion of a wheel having my improvements applied thereto; the view illustrating the sections in various stages-of completeness. Fig. 2 is a view of a section detached, one half of the figure illustrating the samein end view and the otherhalf in transverse section. Fig. 3 is a transverse section of a similar construc tion to that shown in Figs. 1 and 2 but shoiw ing a means of reversing the arrangement of the parts. Figs. 4 and 5 are transverse :'-;8('. tions of blocks or treads provided ni .h binding wires or bands which may be placed as shown or between the springs and the trends. Fig. 5 is a transverse section of a band somewhat like a flat wire rope. Figs. 6 and 7 are respectively a side view of a portion of a Wheel and a transverse section. thereof illustrating an alternative arrangement in which. a spiral or coil spring is interposed between the several sections for the purpose of absorbing shock.

Referring to the drawings, the invention comprises a rim a which may be made of iron or steel and secured by bolts 1) to a felly c. To each of the bolts 1) the ends (1, d of the s ring portions (1, d (Fig. 2) are attached: tliese ends being retained by tightening up the nut b pertaining to the bolt 1). The springs are preferably formed as shown and consist each of a doubled wire arranged to form an approximately elliptical figure (see Fig. 2) the Wire being coild as at (Z d about an imaginary-center situated on the major axis of the ellipse. The ends d, d are respectively connected to floating bars 6, e. the

latter being connected by a leather, chain or other flexible connection f passing over a rollcr'y. This roller is mounted in the end pieces l2, /t to which the block or tread i is secured or from which the latter depends thus constituting a kind ol suspension. The end pieces it, 71/ are n'ovided with lugs or eyes 7:, 72 through which hinge pins Yiflfh are passed; thereby holding the several sections flexibly together.

Upon pressure incidental to the load. or the weight of the vehicle being exerted upon a wheel of the above described construction, assuming, so), three of the sections are in contact with the road surface, the ciicct will be to cause the said three sections to retreat somewhat, the contour of the wheel b66031]: ing to a ccrtaii'i extent flattened owing to the sections on either side of the aforesaid sec-- tions not in contact with the roadway receding slightly. It will however be understood that the aforesaid movement of the several sections is momentary and that all the sections are, in succession, subjected to a similar action. The springs, upon the retreating ac- .tion of the blocks takim place, are caused to contract by the roller g .ing carried radially inwards towards the center of the Wheel, this action having the effect of drawing the ends (1, (Z of the respective springs d, d inwards by means of the suspension The blocks 71 may be shod with a tread 2' which may be composed of leather or other suitable material.

The above described construction maybe reversed as shown in Fi 3 in which the springs (Z, (Z are attached )y' pins or by bolts b", b tothc block or tread 7 i and suspended by means of the saddle or connection f which is arranged about a pin or projection 7 secured to the rim (1; the latter being in turn secured to the telly c.

In order to provide for retaining/ the sections in position in the event of a fr cture occurring and. so enable the car to b run until a suitable opportunity presents itself for replacing them or effecting the necessary repair, the several sections may be bound by means of a Wire or of wires i arranged about the tread sections '5 either below or above the surface of the head in contact with the road way. A band or bands such as i Fig. 5 may be employed with similar effect. In the case of heavy vehicles there may be interposed between the aforesaid sections a spring such as indicated atk in Figs. 6 and 7 the object 2i assess the parts being interchangeable.

Havmg now described my invention what I claim and desire to secure by Letters Patent is:

1. In combination, a telly having two springs of elliptical shape connected thereto by a bolt, the ends of the springs connected to cross bolts, a tread suspended upon the said springs by side pieces, a bolt carried by the said side 'ieces, carrying a roller, a flexible band of ieather connected to the said cross bolts of the springs, the said roller restin the leather band, to flexibly support the tread.

'2. In combination, a telly haying two springs 9i elliptical shape connected thereto,

carrying the head by flexible connections, and two interposed coil springs connected to links between the said treads. i

3. In combination a felly, two springs of elliptical-shape connected thereto by a bolt, the side of the said springs being coiled with the center of the coil in the major axis, bolts carried by the ends of the said s rin s,

a flexible leather band connected to t e said bolts, a roller, carried by a through bolt in the said tread resting upon the said leather band supporting flexibly the tread, and side pieces 7 connected to the said treads through which is passed a connecting bolt to make the heads continuous.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.-
